if vacuum has virtual particles it should have temperature right.? If a perfect vacuum exists ie without any virtual particles..whats temperature of this .is it zero.?
No, the vacuum of space does not have a specific temperature. Temperature is a measurement of the average kinetic energy of particles, and since there are very few particles in a vacuum, there is no temperature.
Yes, objects in a vacuum can have a temperature. Temperature is a property of matter, and even though a vacuum has very little matter, objects placed in a vacuum can still have a temperature.
A perfect vacuum, which has absolutely no matter, does not have a temperature. Temperature is a property of matter, and without matter, there can be no temperature.
Space is not considered to be near absolute zero temperature. In fact, the temperature of space can vary greatly depending on the location and the presence of matter. However, areas of space that are far from any stars or planets can have extremely low temperatures due to the lack of heat sources.
No, a vacuum cannot have a negative temperature. Temperature is a measure of the average kinetic energy of particles, and since there are very few particles in a vacuum, there is no way for the average kinetic energy to be negative.
